DOOR-FASTENER.

SPECIFICATION forming part of Letters Patent No. 759,673, dated May 10, 1904.

Application filed August 8, 1903. Serial No. 168,811. (No model.)

To all whom it may concern:

Be it known that we, CnAnLEs COLEMAN and ALTON N. GREGORY, citizens of the United States, residing at Index, in the county of Snohomish an d State of Washington, have invented new and useful Improvements in Door-Fasteners, of which the following is a specification.

This invention relates to door fasteners or securers, the object in view being to provide a simple, convenient, reliable, and portable door-fastener which may be readily applied to any ordinary hinged door for the purpose of firmly locking said door or securing the same in its closed position without the aid of the ordinary key-operated lock or bolt, the device being especially adapted for the use of travelers, tourists, and the like.

With the above general objects in view the invention consists in the novel construction, combination, and arrangement of parts, as

hereinafter fully described, illustrated, and

claimed.

In the accompanying drawings, Figure 1 is a horizontal section through a suflicient portion of a door and jamb to illustrate the application of the improved door-fastener thereto. Fig. 2 is an enlarged detail perspective view of the fastener, and Fig. 3 is a longitu dinal section through the fastener.

Like reference-numerals designate corresponding parts in all the figures of the drawings.

For convenience in illustrating the application of the improved door fastener or securer we have shown the same applied to an ordinary door 1 and jamb 2. The fastening de vice consists, essentially, of a metal bar or strip 3 of suitable length, one end of which is provided with an offset or shoulder A, which under the preferred embodiment of this invention is formed by bending the strip, as shown in the drawings, to form said shoulder, the latter being adapted to be placed in engagement with the keeper 5 of the jamb,\vhicli keeper ordinarily receives and engages the latch or locking bolt with which the door is provided. The inner surfaces of the angularly-bent portions of the bar constituting said projection 4; form the sides of substantially a =shaped recess, as shown, adapted to receive the end of the usual door-latch (when the door is closed) in the event of the door being equipped with such a latch.

In addition to the catch 4, which will be termed the lixed or stationary catch, the fastening device is provided with a movable or adjustable catch 5, the same being provided upon its inner face with teeth 6, adapted to engage correspondingteeth 7 on the outer face of the bar 3. The adjustable catch 5 is also provided with one or more projections or lugs 8, which are movable back and forward in a slot 9, extending lengthwise of the bar 3 and from a point adjacent to the fixed catch 4 to a point near the opposite or outer end of the bar, as shown in Figs. 2 and 3.

The adjustable catch 5 is further provided with athreaded stem or shank 10, which passes through the slot 9 and upon which is placed a thumb-nut 11 for clamping the adjustable catch against the bar 3 and holding the teeth 6 and 7 in interlocked engagement with each other, thus preventing any possibility of the catch 5 being forced outward along the bar 3.

The outer end portion of the bar 3 is bent to form a curved and slotted extension 12, so that the adjustable catch 5 may be moved outward to the extremity of said extension for the purpose of getting the same out of the path of the door 1 as the latter is closed and opened. The extension 12 also forms a convenient handle for placing the fastening de- Vice in position and removing it therefrom.

In operation the lixed catch 1 is engaged with the keeper 5 for closing the door. The door is then closed, as shown in Fig. 1, while the adjustable catch 5 is on the curved and slotted extension 12. After the door is closed the catch 5 is pushed along the bar 3 until it is brought into engagement with or in proximity to the door, as shown in Fig. 1, in which position it is clamped by the thumb-nut 11, thus effecting a positive interlocked engagement between the teeth 6 and 7 and preventing the door from being opened from the outside by unauthorized persons.

Having thus described the invention, what we claim as new, and desire to secure by Letters Patent, is

The herein-described door-fastener consisttoo ing of a longitudinallyrslotted bar having a said fixed catch being formed With a recess curved slotted extension at its outer end, a adapted to receive the projecting end of the fixed catch or shoulder at or near the inner knob-operated latch of the door.

end of the bar, an adjustable catch movable In testimony whereof We aflix oursignatures 5 lelngthxvise of the bar and prolvid'ed with teeth in presence of two Witnesses.

ac aptec to engage corresponc ing teet 1. on '0 1e 1 T bar and further provided with a threaded shank movable in the slot in the bar and also i along the curved and slotted extension, and a clamping-nut engaging the threaded shank, substantially as and for the purpose specified,
